Now, on your own, draw the following and list the number of valence electrons

Valence electrons are the electrons in the outermost

energy level of the atoms of an element.

Be

# of valence electrons = 2 P: 4N: 5

P+: 4e-: 4 N: 5

-

This is the outermost energy level

These are the electrons in the

outermost energy level

Valence electrons are the electrons in the outermost energy level of the atoms of an

element.
